Getting session auth_data

[gerasiovM]

I am currently learning how to work with the ESAPI and the TPM and I am trying to recreate the "tpm2_createak" tool using python. I've encountered a problem where the tool uses "tpm2_get_session_auth_value" which works by returning session->input->auth_data, but such functionality is not present in tpm2-pytss. How would I set about getting that auth value?

I can't find the tpm2_get_session_auth_value function when browsing the tpm2-tools source, but I assume it's set by a command line option, so you can just keep the auth value you pass somewhere in your code and reuse it when needed
